Rebuilding a Database Catalog
You can clean up resources and redeploy your Database Catalog using your existing image, or the latest image. You might want to rebuild your Database Catalog to get a feature in a later Database Catalog image, to perform housekeeping, or to troubleshoot a problem.
Upgrading your Database Catalog also rebuilds it. Rebuilding the Database Catalog redeploys resources in the cluster while keeping the configurations and other settings you made.
You can rebuild the Database Catalog in the following ways:
- Using the Beta version DW CLI
- Using the Rebuild button in the UI
- Using the Upgrade button in the UI
In this task, you rebuild the Database Catalog using the Rebuild button in the UI.
- Rebuilding deprecated versions of the Database Catalog is not supported and will fail.
- Rebuilding does not preserve the changes you made directly, using kubectl
for example, to cluster resources in the affected namespaces.
Changes you make to the Database Catalog using either the UI or CDP CLI are preserved.
- You must obtain the DWAdmin role.
- To preserve Hue documents, such as saved queries, you need to save a backup of the documents as described in Backing up and restoring Hue documents.
- Log in to the CDP web interface, navigate to , and select your Database Catalog.
